Y M E m m m E M EM WWW R H w, HA PL DISPLAY PACKAGING STRUCTURE BACKGROUND OF THE INVENTION 1. Field of the Invention v This invention is directed generally to the class of paperboard containers where the packaged article is partly, at least, exposed for display.

2. The Prior Art Display cartons of the prior art as exemplified in Powers, et al. U.S. Pat. No. 3,360,117, Hanson et al. US. Pat. No. 3,360,118, and Hanson, US. Pat. No. 3,252,566 are directed to shadow panels flanking the displayed and packaged article. Where the articles are light, intermediate panel stiffening is not required, but where heavy, an intermediate panel for such stiffening is required. Where the packaged article is inordinately heavy, some structure for stiffening the intermediate panel should be provided.

SUMMARY OF THE INVENTION The structure according to the present invention makes it possible to stiffen the intermediate panel of a display carton of THE DRAWINGS FIG. 1 shows unitary paperboard blank for forming a display carton according to one embodiment of the invention;

FIG. 2 shows a blank different from that seen in FIG. 1 for forming a carton according to another embodiment;

FIG. 3 is a perspective view of a display carton constructed inaccordance with either embodiment;

FIG. 4 is a vertical sectional view through a carton constructed with the blank of FIG. 1;

FIG; 5 is a horizontal section, taken along the line 5-5 looking in the direction of the arrows;

FIG. 6 is a vertical section through a carton constructed with the blank of FIG. 2; and

FIG. 7 is a horizontal section taken along the line 7-7 of FIG. 6, looking in the direction of the arrows.

Referring riow particularly to FIGS. 1 and 3 of the drawings, the display carton according to the invention is referred to by the reference number 10 in FIG. 3, and is constructed from a unitary paperboard blank 11 seen in FIG. 1. Blank 11 consists of a first side panel '12 joined to a front panel 14 by a hinged connection 13. An opposite side panel 17 is joined to the front panel 14 by a fold connection 16, and a rear panel 18 is joined to the opposite side panel 17 by a fold connection 19.

Intermediate panel 23 is adapted to be reinforced by a reinforcing flap 28 foldable with respect to the intermediate flap 23 along a diagonal. score line 31. A transverse slit 32 separates the glue flap 26 from the reinforcing flap 28.

Intermediate panel 23 has an opening 33 therein defined by a generally transverse cut edge 33A and by spaced side edges 33B and 33C extending from out edge 33A. Side edges 33B and 33C converge slightly with respect to each other. Opening 33 is further defined by a generally arcuate segment 33D which connects with cut edges 33B and 33C at their divergent ends.

It shouldbe noted at this point that the blank 11 seen in FIG. 1 has its inside face exposed, from which position the steps of forming a display carton as seen in FIG. 3 can be con-- structed. In the steps of forming the carton seen in FIG. 3 from the blank 11, the reinforcing flap 28 is folded along its diagonal score line 31 against the intermediate panel 23, reinforcing flap 28 having a glue patch on the reverse side of blank 11, flap 28 is folded backward out of the plane of the paper as panels l2 and I7.

seen in FIG. 1. Reinforcing flap 28 has a pair of spaced reinglue flap 26 brought substantially into a position of juxtaposition with the score line 19, the glue flap 26 having its glue surface now exposed to view.

The rear panel 18 and the intermediate reinforcing panel 23, which are now in face-to-face relationship, are then folded as a unit along score line 19 with intermediate reinforcing panel 23 in contact with the front panel 14. The underside of glue flap 21, which is coated with glue, is now exposed, and the first side panel 12 is then folded along score line 13 against the glue strip on glue flap 21. When these folding and gluing steps are completed, carton 10 is partially set up in the form of an essentially boxlikeenclosure consisting of front panel 14, intermediate panel 23 and rear panel 18 in spatial relationship in the order named. v

The carton seen in FIGS. I and 3 is provided with end walls, one of said end walls being formed by end closure flaps 39 and 41, foldable respectively along score lines 42 and 43, and respectively. with side panels 12 and I7, and an end closure panel 44, foldable with respect to the front panel 14 along a .score line 44A. End closure panel 44 has a tuck-in flap 46 which is folded against the rear panel 18.

The intermediate panel 23 is adapted to provide structure for locating an article of commerce, which may be more or less cylindrical in form and adapted to fit within the opening 33. Intermediate panel 23 is also provided with closure means defining an opposite end wall for the carton 10.

Intermediate panel 23, see FIG. 4, is accordingly bent slightly along transverse score lines 55 flanking the opening 33 in intermediate panel 23, there being an end closure panel 53 foldable along a score line 54, and having a tuck-in flap 56 extending along the inner side of the back panel 18. The lower end wall, including the end closure flap 53, also includes lower end closure fold in flaps 48 and 49, foldable respectively along score lines 51 and 52 and connected respectively to the side Structure is provided for flanking the opening 33 with shadow panels which serve also to reinforce the walls of the opening 33. To this end the front panel 14 is slit longitudinally thereof along a slit line 59, and also transversely thereof along a slit line 61, slit line 61 being located approximately midpoint of the length of the front panel 14.

panels 57 and .58. As seen in FIG. 5, the shadow panels 57and 58 are adapted to be foldable with respect to the front panel 14 along their respective score lines 13and I6, the respective flaps 64 and 66 being seen in proper position in FIG. 5, and the flaps 64 and 66 embracing sides of the opening 33 in the intermediate flap 23.

It will be seen that the article of commerce, not shown, can be located properly within the opening 33, the ends thereof being held between the reinforced edge 33A and the end closure panel 53. If the article is a cylindrical one, it is located properly by reason of the arcuate segment or edge 33D.

Referring now particularly to FIGS. 2, 6 and 7 of the drawings, there is shown another embodiment of the invention resulting, when the steps of folding and gluing are completed, in a carton having the same general appearance as the carton shown in FIG. 3. In this embodiment of the invention, and with particular reference to the blank 70 seen in FIG. 2, the placement of the glue upon the blank 70 is on the inside thereof, rather than on the outside as seen with the embodiment of FIG. 1. a r

In this embodiment of the invention, the reinforcing flap 28 is first folded along the score line 31, the two tabs 34 and 36 of reinforcing flap 28 flanking the sides of the opening 33, and having glue thereon, being glued thereto at such sides. Following the gluing of the reinforcing flap 28, the intermediate panel 23 is folded along the score line 22, glue flap 26 of the intermediate panel 23 engaging the inside of the opposite side panel 17.

It may be noted that the strut flap 35 of the first embodiment is designated in the present embodiment by a reference numeral 30 (best seen in FIG. 2) and is foldabie into position with respect to the intermediate panel 23 along a score line 30A. The reinforcing flap 28, which is foldable against the in termediate panel 23 and adhered thereto along the tabs 34 and 36, has a notch 30B therein to accommodate folding of the strut.

Following this operation front panel I4 and first side panel 12 are folded at score line 16 to the glue panel 21 which has glue placed thereon on the side opposite to that seen in FIG. 2.

At the completion of this iast operation the front, rear, and opposed side panels, together with the intermediate panel 23, define a boxlike enclosure.

The embodiment seen with respect to FIG. 2 is substantially indentical with that seen with respect to FIG. 1, excepting that the top closure flap 44, together with its tuck-in flap 46, extend from panel 18, as seen in FIG. 2, rather than from panel 14 as seen in FIG. 1. Such differences in location of the closure flap 44 result in minor differences in the closing of the carton, and particular attention is called to the assembly of the carton of FIG. 2 as seen in FIGS. 6 and 7 of the drawing.

In all other respects the carton formed from the blank 70 seen in FIG. 2 is identical with the form of the carton seen with respect to FIG. 1.

We claim:

1. A display carton for holding and displaying an article of commerce, said carton comprising:

a. front, rear and opposed side panels defining a boxlike enclosure;

b. an intermediate panel extending between said opposed side panels in spatial relationship with said front and rear panels;
